This is a discussion on MAF vs Throttle Body within the General Help forums, part of the LSx Technical Help Section category; Does it make sense to increase to a larger capacity MAF while keeping the stock 78mm Throttle body?...

    Larger MAF really won't get you much, but going to a larger TB will. MTI makes a really nice TB, got me 12 at the wheels. My Zo6 MAF did nothing...

    I know with the GTO's you can go with a Zo6 Maf, without tuner problems, but the aftermarket ones have to be totally removed and back to stock to be tuned.
